Title: Controlling device for wound-rotor induction motor
Inventor: WATAMORI OSAMU
IPC: H02P23/00
Filed: 1980-05-26
Abstract: PURPOSE:To eliminate the unstable speed duration in the starting and the speed control of a wound-rotor induction motor by providing an operation limiting circuit having a timer function at the secondary resistor side and enabling arbitrary variation of the resistance value operating time. CONSTITUTION:A liquid resistor 5 varying its resistance value upon elevational movement of an electrode 7 is connected as the secondary resistor to a secondary circuit. A limit switch 9 for detecting the position of the electrode 7 is provided at the electrode of the resistor, and the electrode position signal from the switch 9 is inputted to an operation limiting circuit 10. This limiting circuit 10 has internally a timer, serves to open the output contact 10b during the time preset by the timer upon reception of the electrode position signal from the switch 9 to isolate a normal or reverse rotation signal from an operation switch 8, and limits the operating time of the elevational movement of the electrode. Since the limiting time can be altered by varying the set value of the time, the operating time of the electrode 7 can be arbitrarily altered without varying the construction of the liquid resistor.

Title: Magnetic head with waveform asymmetric correction
Inventor: NAKAGAWA YOSHIHISA
IPC: G11B5/265
Filed: 1988-03-24
Abstract: PURPOSE:To inexpensively reduce waveform asymmetry generated from a magnetic head by the head itself by bi-secting a read/write coil, and loading those coils on the head separately. CONSTITUTION:The read/write coil is bi-sected to the read/write coil 1 and the read/write coil 2, and they are loaded on the magnetic head 4 separately. Here, a difference is generated in the magnetic resistance of a read/write head 4 observing from each coil, and unbalance is generated due to the difference in a write direction of the strength of a write magnetic field. By selecting the direction of an erasure magnetic field so that generated waveform asymmetry and the waveform asymmetry generated by the erasure magnetic field can be offset mutually, it is possible to reduce the waveform asymmetry by the head itself. Also, in such a case, no influence is given on resolution or reproducing efficiency, etc.

Abstract: PURPOSE:To process smearing-out of all graphic in a high speed by performing the smearing-out operation successively in accordance with boundary line decision results of closed areas and retrieval set conditions of ranges to be smeared out in closed areas based on said results. CONSTITUTION:When receiving output data other than data ''0'' from a data ''0'' decision circuit 5, a final point search circuit 11 outputs data indicating the final point to an other area decision circuit 12 if this data exists. The other area decision circuit 12 decides presence/absence of parts to be smeared out in the other areas in the same horizontal direction as the search direction of the final point search circuit 11.
